Benefits of technology

The system effectively increases magnetization, reduces noise interference, and allows for precise measurement of nuclear magnetic resonance signals, enabling accurate analysis of spin-spin relaxation parameters and gyromagnetic ratios, thereby improving signal-noise ratio and measurement accuracy.

Problems solved by technology

However, the NMR still has a defect, i.e. the signal of the low-field NMR being far smaller than that of the traditional NMR system.

Abstract

The invention provides a low-field nuclear magnetic resonance system for measuring a magnetic resonance signal of an object. The low-field nuclear magnetic resonance system includes a pre-magnetization module, a uniform magnetic field coil module, a pulse and receiving coil module, a filter amplifier module, a signal acquisition module and a processing module. The pre-magnetization module is used to establish a pre-magnetization field in the object to increase magnetization of the object. The uniform magnetic field coil module is used to change a resonance frequency and background magnetic field intensity of the object during nuclear magnetic resonance measurement by regulating a magnetic field of the coil. The processing module further includes a programming object for controlling timing processing and signal analysis of the measurement process.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a low-field nuclear magnetic resonance system, in particular to a low-field nuclear magnetic resonance system for pre-magnetizing an object to be measured and capable of adjusting a resonance frequency and background magnetic field intensity during regulation nuclear magnetic resonance measurement.[0003]2. Description of Related Art[0004]From the viewpoint of quantum mechanics for the existing nuclear magnetic resonance (NMR) technique, as the proton number and the mass number are of an odd number, the magnetic quantum number (I) of a nucleus is not zero. For example, for hydrogen, I=½. In such a situation, if the nucleus is placed in an externally applied magnetic field, the spin magnetic torque will be split into two energy levels, i.e. a low energy level of forward magnetic field (upward spin magnetic torque) and a high energy level of reverse magnetic field (downward spin magnetic torque). T...
